npcx: Correct the image copies indication bits for npcx9
In npcx5/7, we use two reserved bits in the BSC1 register (offset 0x07
of the MDC register) to indicate what the current image copy is.
In npcx9, these two bits are used by the booter. We need to change them
to another two empty scratch bits which are not used by the booter.
BUG=b:165777478, b:200642229
BRANCH=none
TEST=pass "make buildall"
TEST=check the related bits changed by "sysump ro" and "sysjump rw"
TEST=jump to RW & check sysinfo after reset-pin/watchdog/debug reset
